If you really do have all the requirements -- especially for the video card and video memory -- you may be having a problem with the DRM. The game may be trying to activate online the first time you play it. If it fails, it will kick you out.

According to the specs I found, the game requires a video card with at least 256MB of discrete video memory.

sorry it took so long to respond. the game installed fine. i have to turn my anti-virus off because it says something in the game is a virus 9 this is apparently a problem with the game 0 i have the disc version. when the splash screen comes up it then goes back to the desktop and says resolution mismatch. i have tried different settings but it still comes up res. mis. i have the computer hooked up to a tv but i am going to try my monitor and see if it's a hardware problem. if you have any ideas please feel free. thanks.
